How this site works
Pick a question you care about, answer honestly, and read the explanation together with your scores. A number on its own is easy to misread.
2. Answer as you are
Answer for how things have actually been recently. A scale measures the frequency you report, not the person you wish you were.
3. Read the guide with your result
Read the guide under the test and the knowledge articles before deciding whether to retake it or talk to someone about it.
What a score can tell you
A score describes how often you reported certain experiences recently. It is useful for noticing patterns and preparing a conversation.
What it cannot tell you
It cannot diagnose a condition or judge a person. A high score is a reason to look closer, not a verdict.
